Abstract (en)
[origin: EP3089249A1] A method is provided for producing a platinum alloy-containing fuel cell electrode catalyst with high activity which is suited for its industrial mass-production. The method for producing a fuel cell electrode catalyst includes a step of preparing a dispersion in which particles of a fuel cell electrode catalyst precursor including a platinum alloy is dispersed in an electrolyte solution, and a step of alternately subjecting the dispersion to bubbling with an oxidizing gas and to bubbling with an inert gas or a reducing gas.
